Choose Chroma if you need:
Feature | ![]() | ![]() |
---|---|---|
Architecture | Client-Server | Embedded/Server |
Setup Time | 15 minutes | 5 minutes |
Max Vectors | 100M+ per node | ~10M (soft limit) |
Query Latency | 10-50ms | <100ms |
API Support | REST, GraphQL, gRPC | Python, JS APIs |
Clustering | Built-in | None |
Resource Usage | 8GB+ RAM | 2GB+ RAM |
Open Source | Yes (BSD-3) | Yes (Apache 2.0) |
Weaviate is built as a complete database system with production features like replication, sharding, and monitoring built-in from the start.
Key Insight: Weaviate trades simplicity for feature completeness and production readiness.
Chroma prioritizes developer experience with a simple embedded database that requires zero configuration and minimal setup.
Key Insight: Chroma's simplicity makes it perfect for getting started but limits advanced use cases.
Note: Performance is comparable for small datasets, but Weaviate scales better to larger deployments.
Weaviate
Built-in sharding and replication, can scale to billions of vectors across multiple nodes
Chroma
Single-node only, must implement custom sharding for scale
Weaviate
Higher baseline requirements but efficient at scale with proper configuration
Chroma
Minimal resource usage, perfect for development and small deployments
Scale | Weaviate | Chroma |
---|---|---|
Development (100K vectors) | $0 (local) | $0 (local) |
Small (1M vectors) | $200/mo | $20/mo |
Medium (10M vectors) | $500/mo | $100/mo (limits) |
Large (100M vectors) | $2K/mo + DevOps | Not feasible |
Enterprise (1B+ vectors) | $10K+/mo + team | Not possible |
For Weaviate:
For Chroma:
import weaviate client = weaviate.Client("http://localhost:8080") # Create schema class_obj = { "class": "Article", "properties": [{ "name": "content", "dataType": ["text"] }] } client.schema.create_class(class_obj) # Add data client.data_object.create( data_object={"content": "..."}, class_name="Article", vector=embedding )
import chromadb # Create client and collection client = chromadb.Client() collection = client.create_collection("articles") # Add documents collection.add( documents=["..."], embeddings=[embedding], ids=["doc1"] ) # Query results = collection.query( query_embeddings=[query_vector], n_results=10 )
